WELL BORING AND SPECIFICATION forming part of Letters Patent No. 501,261, dated July 11, 189e,

Application tiled November 5J 1892. Serial No. 451,068. (No model.)

To all whom it may concern:

Be it known that I, CHARLES WILLIAM WALKER, a citizen of the United States of America, residing at Blue Springs, in the county of Gage and State of Nebraska, have invented certain new and useful Improvements in Well Boring and Drilling Machines, of whichthe following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a new and improved well boring and drilling machine, the same being mounted on Wheels and capable of being transported from place to place ready for use.

The invention has for its object,prmari1y, to provide cheap, simple and highly efficient mechanism whereby a boring and drilling action can be readily imparted to a well-forming tool; and it comprises the detail construction, combination and arrangement of parts, substantially as hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings-Figure 1 is a plan view of my improvedboring and drilling machine. Fig.2 is a side view thereof parts being broken away. Fig. 3 is a rear end view. Fig. 4: is a view ofl the boring attachment or driver, a portion being broken away. Fig. 5 is a detail view, showing the clamp. Fig. 6 is a detail. f

Referring to the drawings, A designatesthe frame or body, and a the carrying wheels upon the axle of which said frame is mounted.

a is a derrick or extension, secured to the rear end of frame A and formed in two parts or sections connected by hinges a2 and said derrick is braced by guy ropes a. To this derrick are secured upper and lower sets of parallel guide rods 01.8 and braces a4.

B is the boring tube guided by rods a3, and suspended by a rope or chain h connected to ayoke b secured to pipe B, and passed over a vpulley h2 at the upper end of derrick a', and connected at its outer, free end to a Windlass C mounted in thesdes of frame A'. To the shaft of this windlass is secured a gearwheel C with which is designed to engage, at will, a pinion d so secured on a shaft d mounted in frame Aas'to revolve therewith,

but capable of being moved into or out of engagement with said gear-wheel by a lever D,

fulcrumed at cl2, said pinion being in the forked end of said lever. A sprocket-wheel cl3 is secured upon the outer end of shaft d', and around it is passed a sprocket chain d4 which also encompasses a sprocket wheel e on a main operating shaft E at the forward end of frame A. This shaft E is mounted in said frame, and upon one end is secured a bandwheel e around which is passed the driving belt (not shown) leading from any suitable motive power. Upon the other end of this shaft E is a sprocket-wheel c2 around which is passed a sprocket chain e3 which encompasses a` sprocket wheel f loosely mounted on a double-crank-shaft F j ournaled in frame A. A sliding clutch-collar f capable of always revolving With shaft F is designed to be thrown into and out of engagement with wheel f by a lever f2 fulcrumed at f3 and connected, toa cranked operating rod f4 which leads to the rear end of frame A.

To the cranked portions of shaft F are connected the outer ends of piston rods g of two pumping cylinders G, which are designed to pump water through pipes g leading from a tankt or other suitable source of supply. By operating ,rod f4 these pumps can be thrown into or out of operation. A balance-wheel I-I is secured on a shaft h journaled in frame A, and a pinion h on said shaft gears with a wheel h2 on crank-shaft F. To a cross-pipe g2 ofY pumping cylinders G is connected one end of a hose or exible tube I,the other end of which is extended into the upper end of boring pipe B, whereby water can be supplied to said pipe to vlioat'the sand, dirt, &c. loosened inthe boring operation.

J is a Walking beam or lever fulcrumed on a cross-rod j of frame A, and extended longitudinally the length of said frame. This beam is moved up and down by an S-shaped cam secured on operating'shaft E, and having rollers j between its' parallel side-bars, which rollers strike against the end of the beam and force the same downward. The rear end of this beam has an oblong opening 7"2, in one end of which is africtional roller ja. The boring tube B is projected through said IOO opening, and is secured by a strap or chain j* when it is desired to drill through rock or other hard substance.

K is the driver or attachment for rotating the boring tube and its tool t. lt consists of a frame 7.; secured by bars lo to frame A, and capable of being held elevated when out of operation by pivoted hooked arms 7a2 secured thereto and engaging eyes 7e of frame A.

Mounted in a cross-piece 7c3 of frame k is a hub or sleeve 7a4 to the lower end of which is secured, or it may be formed therewith, a bevel gear h5 with which engages a beveled pinion 706 on a shaft k7 journaled in frame k.. From the upper end of hub or sleeve 7a4 project lateral arms 708 having at their outer ends vertical hollow extensions or sockets 109 wherein are secured the lower ends of parallel vertical arms law.

L is a clamp composed of two parts or sections pivoted together at Z, and designed to be rigidly held together at their free ends by a threaded bolt Z after being passed around well tube B. The longer part or section has oppositely curved ends which are designed to be engaged by the vertical arms k1@ of the driver. A sprocket wheel m is secured upon shaft k7 and around it is passed a chain fm which encompassesasprocket-wheelm2loosely mounted on shaft d'. A sliding clutch collar m3 is also secured on this shaft and by means of a lever m4 can be thrown into or out of engagement with wheel 'm2 according as it is desired to operate the driver, power being transmitted to the latter through the sprocket chains m. l Vhen the tool is used for boring through dirt or sand the driver is thrown into operation, but when it is desired to drill through rock or other hard substances, the driver is held up out of the way by means of the hooks arms K2 being made to engage eyes K', (or it may be entirely removed) and a chain or strap is passed around the ends of clamp L, and the walking beam or lever, whereby the boring tube is secured to said walking beam. The operation of the machine being continued the S-lever on the main operating shaft will impart a rocking movement to the walking beam, and cause the raising and lowering of the boring tube and its tool, the suspending rope being supplied as may be required.

My improved machine being portable can be moved from place to place and operated atv any desired point.

I claim as my inventionl.
